What is Null-modem emulator ?

The Null-modem emulator (com0com) is a kernel-mode virtual serial port driver for Windows. You can create an unlimited number of virtual COM port pairs and use any pair to connect one COM port based application to another. The HUB for communications (hub4com) allows to receive data and signals from one COM or TCP port, modify and send it to a number of other COM or TCP ports and vice versa.

    This is simple, solid and did EXACTLY what I needed. This is one of the little tools that I keep around forever to pull out when I need just that.

    Sorry my poor English, this project is very useful for me to debug because I work with ancient devices that require COM port interface only.
